Wordpress - Is there a action hook for the "Empty Trash" button?
I don't think there exist one, but you could create your own, wpse_empty_trash
, with something like this:
/**
* Add a custom hook 'wpse_empty_trash'
*/
add_action( 'load-edit.php', function()
{
add_action( 'before_delete_post', function ( $post_id )
{
if (
'trash' === get_post_status( $post_id )
&& filter_input( INPUT_GET, 'delete_all' )
&& 1 === did_action( 'before_delete_post ' )
)
do_action( 'wpse_empty_trash' );
} );
} );
Then you can use it with your code. Example:
add_action( 'wpse_empty_trash', 'myFunction' );
function myFunction() {
// My code
}
Hopefully you can adjust this to your needs.
